Security Testing

Hi, In SOAPUI free, we of course have the option to mock services.

 

I was wondering about the validity of security testing with SOAPUI free across these mock services..how accurate are they?

 

I appreciate the above would never compare to an actual test of the service, I was just curious - it might prove an easy way to refine the TP etc before actually using the real service?

 

thanks
